What a drag to find a worn hydraulic drain plug when you want to change the hydraulic filter on a DB885.
Guess this is not a big deal for an experienced mechanic but I tried spanners, vice grips and tube pliers to not avail.
I even filed down the bolt into a more hexagonal shape. Then I searched the internet for a solution and found IRWIN Bolt gripers.
Ordered a set from RS-Online for 42Euros and an amazingly cheap DHL delivery for only 5Euros within 24 hours.
Should I be unable unscrew the drain plug even with this carbon hardened steel conical nut cracker, can I go ahead and drain
the oil simply by unscrewing the filter panel just enough for the gasket to dribble the oil ? As long as the bucket underneath is large enough, I cannot see a problem.

Hi, I do exactly what James F has described, although the PTO sump plug should be removed also anyway. I think the problem is often that people, perhaps in the past, could not be bothered to use the correct size spanner - which I think is "Whitworth" size and have damaged the "soft" brass plug. The IRWIN bolt grippers look good, but I have recently removed the pan and not bothered removing the remains of the brass plug. Just give it a good clean. The brass sump plug can leak anyway so they may be best left.
